Journal ArticleDOI

Direct full compensation of the aberrations in quantitative phase microscopy of thin objects by a single digital hologram

TL;DR: In this paper, a two-dimensional fit with the Zernike polynomials of the reconstructed unwrapped phase is performed to remove unwanted aberration in quantitative phase microscopy of thin objects.
Journal ArticleDOI

Automatic focusing in digital holography and its application to stretched holograms

TL;DR: An algorithm for automatically estimating the in-focus image and recovering the correct reconstruction distance for speckle holograms and a comparative analysis has been performed with respect to other existing algorithms developed for DH.
Journal ArticleDOI

A digital holographic microscope for complete characterization of microelectromechanical systems

TL;DR: Digital holographic microscopy (DHM) can be described as a non-invasive metrological tool for inspection and characterization of microelectromechanical structures (MEMS) as mentioned in this paper.
Journal ArticleDOI

Quantitative phase-contrast microscopy by a lateral shear approach to digital holographic image reconstruction.

TL;DR: It is demonstrated that it is possible to obtain quantitative optical phase measurement in microscopy by a new single-image-processing procedure combining the concept of lateral shear interferometry (LSI) within a digital holography microscope.

Embedded optical sensor capable of strain and temperature measurement using a single diffraction grating

TL;DR: In this paper, an embedded optical sensor has a plurality of layers (10-20) and an optical fiber (21) with a fiber grating (28), disposed between the layers (14, 16).
